The main advantage of CleWin is that it runs on a PC under Windows 2000/NT/XP/Vista/7. It is compatible with other layout packages
because it uses the standard CIF and GDS-II file formats. Furthermore, CleWin can read and write the AutoCAD DXF, Gerber RS-274X and
Electromask EMK file formats. High resolution PostScript is available as output format.

Because CleWin is also meant to be used by students a lot of attention is given to the user interface. CleWin is a hierarchical layout editor, i.e.
a layout consists of symbols (also called cells) which may be nested. Editing a symbol in one place will change all other instances of the same symbol.
The basic drawing primitives are boxes, circles, wires and polygons. These are the basic shapes that can be stored in the standard CIF format.
Rings and spirals are automatically generated as wires. The latest version of CleWin fully supports true-type fonts.
Complex polygons can be created using the boolean operations: merge, subtract, xor and intersect.
For example: to create a box with a circular hole in it you just draw a box and a circle and select the subtract command.

Especially for MEMS devices some users like to use AutoCAD. Therefore the DXF file format was added. The default format is CIF because GDS-II only supports polygons and wires. When writing GDS-II other shapes like boxes and circels are converted into polygons.

CleWin supports a maximum of 256 layers.

CleWin (version 3) is available for 1450 euro. This price is for a small
site-licence, i.e. a small company or a research group. For universities, updates are free and downloadable until the version number changes into 4.0. For companies, an update and support contract is offered by PhoeniX BV.

Other utilities

The following utilities are currently available:

A bitmap file (BMP, GIF, PCX) to CIF/GDS-II/Gerber converter for easily including photographs and logos in your layout.

An area calculater for calculating the area/loading of layers in mask files.

A GDS-II to ASCII translator/viewer for checking the structure of GDS-II files.

The utilities are available for free for registered users of CleWin or available separately for 95 euro each.

Other Products

WieWeb software specializes in the development of technical, scientific and mathematical software.

Most of these products are custom made. Some of our larger projects include a parameter estimation program for semiconductor
models and an automatic circuit-topology generator for so-called translinear electronic circuits.

Besides these "serious" applications we also have a lot of experience with creating screensavers. Some example screensavers will be downloadable
from our downloads page in the near future.

Support

The easiest way to get technical support for any of our products is by sending an e-mail to our support department:

You will always receive a reply within 24 hours. Bug reports are given a high priority: usually an update is available within one week.
